Effect of Lipid Profile Parameters on Noise Induced Hearing Loss.

Background: Noise induced hearing loss (NIHL) is an irreversible occupational disease among industrial workers. Recent studies have reported that changes in some metabolic factors such as the serum level of sugar and lipids might have a role in suffering from NIHL among workers exposed to noise. We designed this study to assess the association between lipid profile changes and NIHL occurrence among noise-exposed workers.

Early Failure of Arteriovenous Fistula (AVF): The Effect of Diabetes and Hypertension in a Cross-Sectional Study.

Identification and control of clinical predictors of arteriovenous (AVF) failure can improve the long-term outcome of hemodialysis patients. The effects of these factors on the outcome of AVF are not still clear. So, we aimed this study to compare the effect of hypertension and diabetes on early failure of AVF.

Impact of two ergonomics training on prevalence of upper and lower extremity complaints among nurses.

Background: Musculoskeletal disorders (MSDs) were known as one of the main occupational problems among health-care workers. However, we had some limitations and difficulties for transferring ergonomic concepts to the health-care workers, especially nurses due to heavy work task and insufficient time for that. This study compares the impacts of two ergonomic training methods (lecture and pamphlet) in nurses of an Iranian tertiary hospital on prevalence of their upper and lower extremity complaints.

Determination of a Cut-off Point for Exhaled Nitric Oxide in the Diagnosis of Asthma in an Iranian Population.

Background: Asthma is a major source of global social and economic burden; thus, its early detection is important. Measurement of fractional exhaled nitric oxide (FENO) has been used recently considered a good indicator of asthma and also a sensitive and non-invasive method for monitoring airway inflammation. This study was conducted to determine the cut-off point of FENO for the diagnosis of asthma in the studied population.

Photobiomodulation for spinal cord injury: A systematic review and meta-analysis.

In recent years, photobiomodulation therapy (PBMT) has found many applications in various medical fields. Studies of PBMT on spinal cord injury (SCI) have mostly used laser sources in experimental animal models. The purpose of this study was to summarize studies that have employed PBMT for various kinds of SCI in animals.
